I'm trying to connect to my asterisk using "asterisk -vvvr", setting verbosity to level 3.But it doesn´t work. When I type "core show settings" it shows me "Verbosity: 0".Then I have to set manually "core set verbose 3" to work.

Yes, verbose mode (-vvv) work with remote option (-r).See my other server that is not having the problem I reported:
